Detailed Description
The invention is further described below with reference to the accompanying drawings in combination with specific embodiments so that those skilled in the art can practice the invention with reference to the description, and the scope of the invention is not limited to the specific embodiments.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing the invention and simplicity in description, but do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed in a particular orientation, and be constructed in a particular manner of operation, and thus, the terms are not to be construed as limiting the invention.
A driving waveform debugging method capable of reducing power consumption of electronic paper comprises color-developing particles in the electronic paper and a voltage driving waveform for driving the color-developing particles to move up and down for display, wherein the voltage driving waveform comprises a balance area, a flicker area and a display area, the balance area, the flicker area and the display area are respectively composed of at least 1 group stage, the balance area, the flicker area and the display area are composed of 10 group stages, the balance area is composed of group1 stages, the flicker area is composed of group2 stages, group4 stages, group6 stages and group8 stages, the display area is composed of group3 stages, group5 stages, group7 stages, group9 stages and group10 stages, the voltage driving waveform is refreshed from group1 stages to group10 stages in sequence, each group stage comprises at most 4 timing voltage selection stages, and the voltage selection stages comprise positive voltage selection stages, A negative voltage section and a no voltage section; giving a voltage refreshing frequency of a low frequency of the flicker region, giving a voltage refreshing frequency of a high frequency of the display region, giving a voltage refreshing frequency of a low frequency or a high frequency of the balance region, and staggering a positive voltage section and a negative voltage section of each color-developing particle in the same group stage in different time sequences, wherein the positive voltage section comprises a positive voltage load time and a positive voltage load time, the negative voltage section comprises a negative voltage and a negative voltage load time, and the voltage-free section comprises a voltage-free load time; the high-frequency voltage refresh frequency is a voltage refresh frequency greater than 50 hertz, and the low-frequency voltage refresh frequency is a voltage refresh frequency less than or equal to 50 hertz.
As shown in FIG. 1, in 20 ℃ to 30 ℃ of normal temperature, the electronic paper needs to use (75HZ or 100HZ or 125HZ) high frequency voltage refresh frequency to improve the display effect of the fonts because the fonts are pasted, for example, when the electronic paper with 3 inches uses 100HZ voltage refresh frequency, the average current will reach 5mA, and when the electronic paper uses 50HZ voltage refresh frequency, the average current will reach 3mA, therefore the voltage refresh frequency of 100HZ is 40% higher than the average current power consumption of the voltage refresh frequency of 50HZ, the present application applies different frequency voltage refresh frequency to the balance area, the flicker area and the display area, for example, in FIG. 2, the voltage refresh frequency from group1 stage to group8 stage is 50HZ, shown as A, the voltage refresh frequency at group9 stage is 100HZ or more, shown as B, group10 stage is shown as C, and the voltage refresh frequency at 100HZ or more is shown as C, because the display area mainly determines the display effect of the fonts, high-frequency refreshing is required to be used for improving the font effect in order to solve the problem of blurring caused by mutual erosion of the fonts, the average current for refreshing the screen is only 3.6mA, the current power consumption can be reduced by 28% by applying different voltage refreshing frequencies compared with the mode of completely using the high-frequency voltage refreshing frequency, and the service life of the screen is greatly prolonged.
In addition, for a plurality of color-developing particles, corresponding to a voltage driving waveform, operating in a certain group stage or a plurality of group stages in a balance area, a flicker area and a display area, as shown in fig. 3, the voltage driving waveforms of black color-developing particles, white color-developing particles and red color-developing particles in the group1 stage of the balance area and the group3 stage and the group7 stage of the display area output high voltage and low voltage simultaneously, the output mode of the voltage driving waveform can cause the load of the IC to increase, the IC outputs source high voltage 15V and low voltage-15V, the gate voltage can be pulled down to generate voltage drop, the output capability of the IC is not changed, at the moment, the peak current of the electronic paper reaches 30mA, and the peak current of other group stages is only 20mA, therefore, the application adopts the mode that the positive voltage section and the negative voltage section of each color-developing particle in the same group stage are staggered in different time sequences instead of the same group stage and the same time sequence in the same step When the positive voltage section and the negative voltage section are output, high and low voltages are output at the same time in a staggered manner in a group1 stage, a group3 stage and a group7 stage in fig. 4, so that the load of an IC is reduced as much as possible, the peak value and the average power consumption of electronic paper screen brushing are reduced, the battery endurance time is greatly prolonged, and the service life of the battery is greatly prolonged.
